Thanks marcus ,
That means , if i use i5 processor and make some tweaking in gnuradio in
right areas , i could be able to process my 100 Mhz bandwidth using my 200
MSPS ADC, 32 channel DDC which will only send data of only 3500Khz bandwidth
data to the CPU, in spite of inviting a big overhead to
IF i should require to make the
100Mhz bandwidth to be able to process in my 200MSPS ADC,
Sorry for late reply.
Thanks.

Hi everyone ,
I would like to know what is the actual last converted IF frequency which
is actually fed to the ADC in usrp/gnuradio , since ADC rate is 64MS/s , I
hope it IF should be less than 2xSampling rate of ADC, which implies IF
could not be 70Mhz. So what is the value of IF before entering

Hi guys ,
I Just want to confirm a thing regarding the demodulation of the digital
dat in the gnuradio as the signals are received from the usrp. The doubt
are,
1. Where is the demodulation is implemented in the gnuradio .
2. What demodulation is implemented by default in the urp_rx_cfile ...
Hey guys ,
I am searching the point / code where the c++ part accepts / pick data from
the usrp fifo . I have search out some and could grasp some idea of the
gr_buffer. Can someone guide me in helping me understand how the
usrp_basic.cc , usrp_prims_common.cc etc interacts and take out data
Hi everyone ,
I apologise in advance if i have asked a very insignificant and illogical
question , I am trying to understand the gnuradio programming architecture
so as i can make my own module/block so as i can implement and do some
experiment on my concepts of dsp using gnuradio.Please someone
Hi guys ,
I am trying to know the way how usrp processes when i provide frequency to
the usrp_rx_cfile.py. Please someone eleborate me where i am actually
providing my frequency.
Where my frequency parameter is actually been fixed in which part of the
usrp .. example : Daughterboard , ADC etc.

As i was searching for a book on gnuradio and usrp , i found a book

am not able to get any place to download this book. Can someone

I want to know a thing regarding gnuradio to all the guys out there

Hi everyone,
I am a bit trying to understand the relationship of the gain,offset and

Hi everyone ,
I have been trying an experiment in trying to capture different frequencies
using python thread to alternately capture different frequencies.
what i am trying is like this [ pseudo code ].
#freq_list = [ '222','787']
1: capture 222 using usrp_rx_cfile.py... by supplying freq
Hi everyone ,
I was just wondering if we can capture multiple frequency from usrp
simulataneously.If not why is it so.And if we can , can some one tell me if
we need to change the usrp programming part , means fpga programming /c++
programming / or any.
Thanks all for your concern in advance.
if any solution we have to solve this
problem.
Hope i ll get a response soon, and thanking u all in advance.
